cpu-g version 0.15.0-1ubuntu0 does not launch under Ubuntu 18.04

[Kirill Marchuk]

I've download the deb file from here: http://ppa.launchpad.net/atareao/atareao/ubuntu/pool/main/c/cpu-g/cpu-g_0.15.0-1ubuntu0_all.deb

any attempt to launch the tool leads to crash report

if I run it from terminal, this is what I get as an output:

./cpu-g:26: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.

what am I doing wrong?
